Bit early but such a dull day I'm not expecting much from the PV.

My results for December were:

3.87 kWp, slope 50 degrees, due south, lat 57.15

Total generation: 65kWh

Daily average: 2.1kWh

Generation per kWp: 16.8kWh

Daily average per kWp: 0.54kWh

PVGIS: 62.1kWh

%PVGIS: 105%

Dec 23
Solaredge PV 18kWh
Victron PV 33kWh
Hoymiles PV 11kWh
Enphase PV 1kWh
Graig Fatha WT 1,041kWh
Total RE generation 1,104kWh

Bought 2,926 kWh of electricity which is a split of 72.7%/27.3% in favour of the grid.

Zero gas!

28.67kWh a bad December even without losing the ( too ) mobile array.

On the plus side on the first of January before 11 pm we have already harvested 231Wh and have 192Wp incoming which is better than most days over December so at least here it’s a very very happy new year

Finished the day with a whole kWh ! After December that’s really brilliant

Nowty Towers Power Station
Main 4kW PV system generated 61 kWh which is about 43% below baseline, in fact worst month ever in 13 years.
Total PV arrays generated 136 kWh.

Electric Import was 2244 kWh.
Gas import was 57 kWh.
Out of house EV charging was 176 kWh.
Petrol used in EV hybrid was 0 kWh.
Total imported energy use 2477 kWh

Solar PV / Battery electric export was 75 kWh.
Ripple GF wind farm generated 1655 kWh which is 24% above baseline and a new monthly record.
Total energy offset 1730 kWh

Net energy import (this month) for Nowty Towers 747 kWh

2023 (cumulative) Net Energy Import 1848 kWh

4kw FIT system generated 63kwh - my poorest December since instalation.
5.45kw Non FIT system generated 109.6kwh

Need to do a bit of investigative/monitoring work based on these numbers, as both systems side by side on the same south facing roof but seem worlds away from each other, even when factoring in the additional 1.45kw and better pv efficency.

Stats for the work array for December

Solar Production - 107.3kWh
Self consumption - 105.9kWh
Export - 1.34kWh

Overall building consumption - 2.65MWh
Import - 2.54MWh

Total for 2024

Overall consumption - 27.15MWh
Overall generation - 9.28MWh
Self consumption - 6.27MWh
Export - 3.01MWh


Here's to the sunnier days ahead in 2024!

December figures - 52kWh generated - above PVGIS of 45kWh, but lower than last year of 62kWh.

Total for the year was 4566kWh - above PVGIS of 4054kWh - Happy with that for my first full year

Solar 41.88 kWh just beat last December by 700 w

Total import 3421 ( 2857)
Total export 120


However dec 22 I was using several free car chargers which have now disappeared, which probably saved 400 kWh in December

A bit late on this one, but December 2023:

PVGIS: 190 kWh
Actual: 59 kWh

Absolutely awful.

But for all that Octopus have made the app work for calculating the Flux tariff.

From 01/7/23 to 31/12/23, including saving sessions, 6.4 kWp and 14kWh worth of batteries was cost neutral including gas import and standing charges.
